Or The angle measured in the equatorial plane from a reference point in the sky where right ascension is defined to be zero. Satellite Communications full notes Download ec2045 satellite communication notes notes on satellite communication pdf format. Total service from a single provider 9. High cost for satellite 2. Solar fluctuation may cause comunication of primary power system Severe thermal stress on a satellite.
EC2045 Satellite Communication Important Questions April May 2016 – ECE 8th Semester
Some examples are cokmunication satellites and communications satellites. GPS system for position determination. Explain in detail the operation of a preassigned SCPC network. For more educational update keep visit us.
Launching the satellite Space shuttles carry some satellites into space, but most satellites ec2045 satellite communication notes launched by rockets that fall into the ocean after their fuel is spent.
Every object in a state of uniform motion tends to remain in that state of motion unless an external force satellite applied to it. Firing a rocket motor at apogee is called “apogee kick”, and the motor ec2045 satellite communication notes called the ” apogee kick motor”.
With the aid of a block schematic, briefly describe the functioning of the receive. Give the shape of the ellipse. AKM Apogee Kick Motor is used to circularize the orbit at GEO and to remove any inclination error so that the final orbit is very close to geostationary. Satellite Communications full notes please upload note of ef2045. Describe the general operating principles of a TDMA network.
Relates the orbital planes position to the earth. As the Earth is bulging from the equatorial belt, and keeping in mind that an orbit is not a physical entity, and it is the forces resulting from an oblate Earth which act on the satellite produce a change in the orbital parameters.
The forces due to sun and moon causes the inclination to change at a rate of about 0. Explain about frequencies and polarization, transponder capacity and bit rates for.
Rapid installation of ground network 6. Two planets are shown on orbits that are the same shape, but the larger orbit is 1. Argument of Perigee Perihelion: The time now is This causes the ec2045 satellite communication notes to drift as a result of regression of ec2045 satellite communication notes nodes and the latitude of the point of perigee point closest to the Earth. These are sides of all arcs of great circles, and these sides are defined by the angles subtended by them at the center of the earth.
They usually separate from their payload and crash back to earth. After a few orbits in GTO, while the orbital parameters are measured, a rocket motor Ec2045 satellite communication notes is ignited at apogee and GTO is raised until it is circular geostationary orbit.

Explain the principle behind spectrum spreading and dispreading and how this is. Hence satellite west of ES is more desirable Probability of satellite failure is more during eclipse than at any ec2045 satellite communication notes time.
Satellite Communications full notes, pdf, e-book thank 4 page but need more inf.
Telstar was the first active, direct relay communications satellite. You may ex2045 like: Give the difference between KU-band and the C-band receive only systems. They are more expensive in fuel than east-west station keeping maneuvers.
Small Fading margin 3dB Apogee and Perigee Heights Although not specified as orbital elements, the apogee height and perigee height are often required, the length of the radius vectors at apogee and perigee can be obtained ec2045 satellite communication notes the geometry of the ellipse: When the target altitude is reached the engine is fired in the ec2045 satellite communication notes manner as before but this time the added velocity is planned such that the elliptic transfer orbit is circularized at the new altitude of orbit C.
Orbit Perturbations perturbations of the orbit are the results of various forces which are exerted on the satellite other ec2045 satellite communication notes the forces of attraction of the central, spherical and homogeneous body. Thanks for the upload. Astronomers call this point the vernal equinox. Newton’s Law of Motion:
